GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 485,157, dated October 25, 1892.

Application led February 26, 1886. Serial No. 193,333. (No model.)

To a/ZZ whom it mafyconccrn:

Be it known that I, EDWIN M. KELLOGG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specication.

In the past few yearsa novel form of holder has been introduced and become known under the term crown-disk holder. Such a holder I have described in Letters Patent granted me on the 23d day of March 1886, No. 338,417, and have therein claimed certain combinations into which it enters or by which it. is actuated. This holder consists of a disk with an upturned notched fiange saddled by a shoe and has heretofore been mounted upon a spindle parallel with the tyer-spindle, so that the cord is carried toward the knotter in a plane at right angles to the tyer-spindle. Such arrangement requires, also, that the cord-st rands shall be laid by the binder-arm in the notch nearest the tying-bill and close to the shoe which saddles the iiange; but in practice, owing to the position of the holder-spindle relatively to the tyer-spindle, it has been proventhatthereisgreatliabilityofthebinderarm laying the strand last brought up into both that notch and the notch opposite, so that when the holder-disk begins a revolution the strand will be pulled aside close to the eye of the binder-arm and may be sprung ont of the notch that is just entering the shoe, so as not to be grasped or not firmly grasped. To remedy this and to provide for lifting the cord in its lateral travel toward the knotterjaws so as to be properly `laid and caught between the latter, I incline the holder-spindle so as to raise the side of the holder-disk nearest the tying-bill and depress the side farthest therefrom relatively to the plane of revolution of the tying-jaws, thus insuring that the cord-strands laid by the binder-arm, While they fall into the notch in advance of the shoe, cannot by any possibility reach the opposite notch and that they shall properly engage the tyer and be directed between its jaws as it nears the end of the revolution. Novel means are also adopted to actuate the holder.

Another difficulty experienced in this class of binders is that the strand, being placed about the gavel by the binder-arm, occasionally becomes entangled in the grain and is pushed to one side, so that it does not properly reach the knetter, or so that the binderarm slips past it in the cord-slot andthen bars its proper approach to said knotter. This has usually been provided for by the employment of a tuckereither upon the binder-arm or else above the breast-plate and operated by an irregular flange or groove upon the tyer-cam, involving extra mechanism and eXtra weight. It. being an object to place a minimum of labor on the tyer-cam and to reduce the weight and number of parts as much as possible, those just enumerated are dispensed with and a shoulder or rounded breast is formed upon the binder-arm at such a point and of such easy outline that while readily piercing the iutlowing stream of grain it will by sweeping curved reaches ot the grain-depressing ribs depending from the breast-plate on eaclrside of the cord-slot practically close the cord-slot on the side adjacent to the grain without passing therethrough, thus pushing the strand before it asthe binder-arm carries it around the gavel and bringing it up close to the tyingbill.

Various other improvements are set forth in the ensuing description and pointed out in the claims.

In the drawings, Figure l is a vertical sectional elevation of so much of a binding attachment embodying my invention as is nec'- essary to an understanding thereof.

and 15, views in rear and stubble side'elevation and in section Yof a modification of the invention for the purpose of actuating the holder.

A represents the decking ef a binding attachment er that part which forms the flooring of the grain-chute, and B is the binderarm mounted upon a rock-shaft. therebeneath and provided with the usual concentric guardinger. Above this decking and forming the top of the grain-passage er packing-chamber is the breast-plate C, also slotted for the play of theY binder-arm and having ribs e alongside each under edge of said slot to keep the waist of the gavel from contact with the plate, and above the breast-plate is the main tyershaft D, supported, as usual, in an everhung arm from the post-frame. A bracket D', sleeved upon this tyer-shaft and braced by a stay-rod d, leading te support on the harvester-frame, depends from said shaft and has its feet bolted to and supporting the breast-plate. A bearing d', formed in this bracket, receives the spindle of the knetter er tying-bill E, which, as usual, is formed with a rigid jaw e and a piveted jaw e', the latter being controlled by means of a spring-cam e2, which acts upon the outer side of its heel eX- tension to close it, and a iXed cam e3 upon the stock or bracket, which acts upon the inner side of said heel extension te temporarily open it in order to receive the crossed-ends of the band, the action of the spring-cam imlnediately succeeding to close the jaws, grasping these ends and holding them while the` loop is drawn overV them.

At the upper end of the tyer-spindle is secured a bevel-pinion F, having upon its hub two delay-shoes f and f in differentplanes transverse of the spindle and at an obtuse angle te each other, the lower shoe being intended te hold the knetter at rest during the long interval preceding the next binding eperation, and the upper shoe having for its object to lock it temporarily in position while the bundle is being ejected before it reaches its original or starting peint. YThe teeth of the pinion are cut away from the initial end of the upper shoe to near its rear end, forming a gap f2, one wall of which is about Hush I with said shoe, and the other wall of which is formed by a tooth of the pinion near said rear end, all for a purpose that will presently appear.

Upon the tyer-shaft is mounted the tyercam G, consisting of a wheel er disk provided en the face adjacent to the tyer-spindle with a segment-rack g, not having, as usual, sufficient teeth to give the tyer a complete turn, but less than that number, so that as the tyerpinion passes off of the rack the jaws of the knetter will stop in aposition trending outwardly along the slet in the breast-plate er in the general kdirection of said slot. Beyond this rack, to enga-ge with the upper shoe of the pinion, is a delay-ledge g,of such length as te allow the ejector-fingers G', which come in contact with the gavel at the moment the Shoe rides upon the initial end of the ledge,

to complete their action just as it reaches the farther end. At thisvlatter peint is locateda solitary tooth g2,which, entering and passing along the gap in the pinion, engages with the rear wall or gear-tooth and revolves said pinion just sufficient to bring the knotting-jaws to a position completing their revolution er their original er starting position, pointing right across the line ot' the slet in the breastplate, when the second delay-shoe en the pinien falls upon a succeeding delay-ledge g3, described en a greater radius than the first, to prevent interference, by which the knetter is locked in position until its pinion engages with the segment in the next tying operation. That portion of the slet Hin the breast-plate through which the binder arm plays is straight, as usual, but adjacent to the knetter it becomes oblique, trending toward the knotter-spindle,or, rather, forming a linger h, pro` jeeting from the side farthest from the spindle inte a recess or cut-away portion beneath said spindle and terminating opposite or almost opposite to its axis, at which peint the slot returns slightly inward for a'spaee beneath and about parallel with the knetter-jaws in their transverse position, then curves gradually eutward and obliquely away from the knetter in the direction of the trend of its jaws, when their pinion runs off its segment and the first shoe engages with its ledge.' Thus when the knetter' is stopped at the conclusion of the Vbinding operation, with its jaws directly across the general line of the slot, the cerdstrands as they are laid, first by the recession ofthe binder-arm and then by its approach, will be deflected along the upper or inner edge of the linger and laid on the chin of the knetter close to its spindle and retained there, whether they escape past the end ef the finger er remain upon it te be carried thereever and inte the lower returning reach of the slet by the revolution of the knetter. The slight inward or return curve of tne slot prevents any tendency of the strands te slip along toward the nose of the knetter should they escape from the finger, and in any event the knetter-jaws in their transverse position so completely close the slot that the strands are absolutely barred from passage until they have beentied,while the oblique continuation of said slot allows the band to be pulled from the knetter when the latter has stoppedinits outwardly-trending position. The justmentioned oblique reach of the slot, coupled with the transverse position of the knetter while the band is being laid, willef course insure that that strand which is grasped in the holder and is vpaid out in the recession of the binder-arm immediately after the sheaf has been ejected and the knetter has reached its second or starting position, will be properly deflected and placed upon the chin of the knetter close up te the spindle in the most favorable position for ty- IOO IIO

ing', but it often happens that the strand brought up to be laid alongside of that first or holder strand in the rise of thebinder-arm gets entangled with or pushed aside or retarded by the grain, so that it lags behind the arm, and at the moment itshould enter the oblique reach of the slot is barred therefrom by the arm itself, andso is not properly presented to the knetter. There are objections tothe use of a cord-tucker on the arm itself to obviate this, because it weakens the arm, and, with its accessories, adds so much additional weight to the machine, and an independent cord-tucker above the breast-plate,`

operated from the tyer-cam, although perhaps involving less weight, doesinvolve additional `mechanism and some additional weight, and

although it forces the strand into position for the effective action of the knetter often does so by pullingr slack from the receptacle, leaving that part that is blocked by the binderarm as slack in the band. Instead of adopting any of thee forms I provide a bulbous breast or enlargementi upon the shank of the binder-arm atsuch a point that as this arm rises it will travel close to and practically fol-"1 low the slot or space along the under side of shank of the arm is at the outer extremity of the straight reach of the slot, and the strand` will therefore pass readily into the oblique reach and be deflected by the finger toward the knetter-spindle to rest upon the chin alongside the other strand and parallel therewith. The revolution of the knetter, of course, immediately succeeds this. This breast or shoulder is a mere bulbous enlargement, easily piercing the grain, but of sufficient capacity to close the slot along the under side of the ribs, the edges of which are in contact with and depress the grain. Between these ribs the binder-arm breast cannot pass, but sweeps along them, as stated, pushing the grain as well as the cord before it. It is, therefore, to be distinguished from a tucking- :linger projecting aggressively from the binder-arm.

Outside of the bearing for the tyer-spindle K the supporting-bracket has oblique bearings for the holder-spindle, the lower bearing lo being near to the tycr-spindle or only at such distance therefrom as to bring the holder-disk close to the tying jaws, while the upper one 7c throws the end of the holder-spindle out near to the periphery of the tyer-cam.'

The holder consists of a circular plate or disk K of proper diameter, having at or near its periphery an upturned rim or flange provided with a series of forwardly-set notches k2, giving its outline the appearance of rounded saw-teeth withtheir shoulders set in the direction of revolution. This disk, generally called a crown-disk, is saddled on the side nearest to the knetter by astationary shoe L, the sides or fiaps Z of which pass beyond the bottom of the notches slightly, and the inner height in relation thereto, bringing the disk in a plane oblique to the line of the second strand of cord stretched between the knotter and the nose of thebinder-arm when the latter has encircled the gavel, with its `inner side intersecting said line, and since proper construction requires that the knotter should come close to the inner surface of the breastplate and that the cord should be grasped and held sufficiently low down to enter between the knotter-jaws when they open I find it advisable to cnt away the outer part of the breast-plate, as at L', to allow the farther side of the holder-disk to pass therethrough in order to obtain the proper inclination.

The positive grasping of the cord between the unyielding surfaces would, owing `to the uneven thickness of the cord and the defects known even in the best of binding-cord, result often in imperfectbinding and escaping bundles. Ithas always, therefore, been found necessary to provide for a yielding contact between the holder-disk and its shoe whatever their construction. This is accomplished herein by permitting the holder-spindle to slide in its bearings and placing between the lower bearing or thimble thereon, and a nut` Heretofore the shoe has been bolted to ther bracket or stock at a distance from the holder` disk and has extended thereto from this point of attachment; but in the present invention it is formed with a hub m to embrace the holder-spindle loosely and thestock is recessed above the disk to receive the hub. A

dowel-pin m', passing through a portion of the stock alongside the `bearing for the `spin` die, enters a recess m2 in the web connecting this hub with the shoe proper, 'and thereby holds it against rotation with the spindle.`

Thus in assembling the parts 'the hub of the shoe is slipped over the" spindle and theispinl-A die then placed in its bearings,iwhen all parts of the holder are secured together by `the IOC IOS

IIO

same means that retainY the spindle from slipping out of such bearings. The aps or depending walls of the shoe in this class of holders have also been heretofore made to terminate on the same radial line at their rear; rbut to permit the ready escape of the fag ends of the cord and to cause them to drop outside of the crown-disk, instead of being retained in `the cup formed thereby, I cut away the 'inner flap in advance of the other, so that it shall Arelease the portion of the fag end grasped by it in advance of the outer one, thus insuring that the rotation of the disk shall push the said fag end toward the outer side and that it -shall be dropped from said outer side when released by the exterior flap of the holder.

To the extreme upper end of the holderspindle, adjacent to the periphery of the tyercam, is pinned or fastened a pinion N, which -in the present instance has twice the number of interdental spaces as are found notches in the crown-disk. At the outer edge of the cam, either upon its face or its periphery, is Vdescribed a ledge n, engaging with said pinion, and which for a distance corresponding with the interval between the severing of the cord and the starting of the tyer and holderin the ensuing binding operation is so described, either upon a concentric curve, if upon the face, or upon a radius, if it is upon the-periphery, as to act as a delay-ledge and hold the pinion stationary and the holderdisk consequently immovable; but at a point corresponding relatively to the initial movement of the knotter this ledge terminates and is succeeded by a short oblique or spiral ledge n', which enters the next interdental space of the pinion and causes it to turn sufficiently to carry the notch in the crown-disk, in which the cord has been'laid, beneath the shoe and clamp the cord, and then the succeeding interdental space is engaged by the insetting initial end n2 of the first-named flange or delay-ledge. In traveling along this oblique initial reach of the delay-ledge the pinion will be given an additional turn equal to one interdental space, the purpose of which is to carry the strands which have now been seized by the knotter and clamped between its jaws against the knife and sever them, when the holder comes to rest and is held at rest by the delay-ledge until the succeeding knotting operation commences. The knife 0 j ust mentioned is clamped to the stock in such position as to bring its cutting-edge close against the outer wall of the holder-shoe, between it and the knotter, but a little behind the point where the cord-strands are grasped by the holder at the moment when the tying-jaws receive and close upon them. The onward movement of the holder from the instantthat the tying -jaws have closed and the cordstrands are securely held therein carries these end strands along the under edge of the shoe and immediately against the knife, which eX-A tends below said edge, and they are thereby severed, leaving the main strand still grasped between the shoe and the crown-disk. The stationary knife cannot be employed to the best effect when the knotter-spindle and holder-spindle both lie in a common plane parallel with the plane of movement of the binderarm, and therefore I place the holder-spindle in a plane farther removed from that of the binder-arm-say about half an inch-which insures certainty in the operation of the knife.

In operation, supposing the end of the cord to have been already grasped in the holder in binding the previous sheaf and the binderarm to be still in its highest position and the knotter to have reached its position of rest with its jaws pointing transversely across the cord-slot'and closing it, the binder-arm recedes, laying the cord-strand in the notch in the holder-disk, just in advance of the clamping-shoe, thence over the chin of the knotter, and then upon the deflecting-iinger in the cord-slot, and finally sinking beneath the decking to its own position of rest. Grain is then fed against the strand of cord stretched from the holder to the nose of the binder-arm and across the passage-way or packing-chamber between the breast-plate and decking until sufficient has accumulated to form a'sheaf, when the binder-arm rises, carrying the cord up around the gavel, through the slot in the breast-plate, which, as already stated, is closed by the enlargement or breast on the shank of the arm, so as to push the strand along before it, and finally laying it upon the detlecting-iinger over the chin of the knotter alongside the first strand and in the same notch in the disk in which the first lies. The arm comes to a stop and immediately the revolution of the tyer-cam, which by means of its provisions for delay has held the holder and the knotter stationary until that moment, brings the gearsegment into engagement with the knotterpinion and the first oblique ledge at its periphery' into one of the interdental spaces of the holder-pinion and the knotter and holder begin to revolve, the revolution of the holderdisk carrying the two strands of cord beneath the shoe and laterally toward the knotterspindle, so as to meet the knotting-jaws as they come around. At the proper moment these jaws open to receive said strands, at just which time the holder-pinion reaches the end of the oblique ledge7 which has been actuating it, and the revolution of the disk momentarily ceases. Then the knotterreaches the spring-cam and its jaws are immediately closed, grasping the strands which have been received between them, and their revolution at once ceases, leaving them directed outwardly along the slot in the breast-plate, and now the second oblique ledge at the periphery of the tyer-cam, which has already engaged with the holder-pinion, begins to act thereon, turning the disk a slight distance farther, carrying the strands against the stationary knifeedge and severing them, when it also comes to a stop and is thereafter held at rest by the IOO IIO

delay length of its actuating-ledge. As soon as the strands are severed the ejector-fingers, by this time brought round by the revolution `of the tyer-shaft, strike the sheaf and push it forcibly from the machine, wrenching the knotfrorn the tying-bill as they do this. Then the knetter-pinion is struck by the solitary tooth and turned just sufficiently to bring the bill to its starting position, with its jaws across the cord-slot, and the lower delay-shoe resting on the outer delay-ledge to lock it in "position until the succeeding binding opera- 1.
